This is difficult,these are the people i stayed with years ago,a place called sitangkai,the high street floods every day with the incoming tide,they used to say that the badjao come ashore once in their lifetime and thats when they die,the kids swim before they can walk,their entire income used to be from the sea,nowadays they smuggle goods and people,and some beg in the harbours of cities like cebu diving for coins thrown from passanger boats.
